Abstract (en)
[origin: WO2017031228A1] The present application discloses an authentication method used in a QKD process, and further discloses additional authentication methods and corresponding apparatuses, as well as an authentication system The method comprises: selecting, by a transmitter according to a basis selection rule, a basis of preparation for transmitter authentication information that is generated with a first pre-provisioned algorithm and varies dynamically, and transmitting quantum states containing key information and the transmitter authentication information; and measuring, by a receiver, quantum states of the transmitter authentication information according to the basis selection rule, and ending the QKO process if a measurement result is inconsistent with corresponding information calculated with the first pre-provisioned algorithm.
